Application March 22,

10 Claims.

This invention relates to embroidery machines, and more particularly to the shuttle meansof the stitching mechanism of such machines, and which is cooperatively associated and coacts with fabric or hosiery holding devices of the type disclosed in my Patent 'No. 1,482,680, and my copending patent application Serial No. 132,379 filed of even date herewith.

Among the objects of my invention are, to

provide novel shuttle means for embroidery machines which operates more efficiently, freely and precisely than the means heretofore available for this purpose, and which makes it possible to obtain better results from machines, such as hosiery embroidery machines, to which my invention is particularly applicable.

With these and other. objects in View, which will become apparent from the following detailed description of the illustrative embodiments of the invention shown in the accompanying drawings, my invention comprises the novel elements, features of constructionand arrangement of parts in cooperative relationship, as hereinafter more particularly pointed out in the claims;v

In the drawings: Figure 1 is a front elevational view of my novel shuttle means, illustrated in association with other parts of a hosiery embroidery machineyvith which it is adapted to cooperate; Fig.2 is a side'sect'ional view, taken substantially as indicated by the arrows 2-2 on Fig. 1; "Fig. 3 is a rear elevational view'ofFig. 1, and

shows certain of the parts in another position; v Fig. 4 is an enlarged sectional view taken substantially as indicated by the arrows fl4 on Fig. 2;

Fig. 5 is a cross sectional view,taken as indicated by the arrows 5,-5 onFig. l; and Fig. 6 is an enlarged 'detail sectional view, taken as indicated by the arrows 66 on Fig. 1.

For illustrative purposes, 'a practical form of my invention will be hereinafter described as embodied in well known hosiery embroidery machines, In such machines, a multiplicity of individual hosiery holding frames or devices are means with respect to cooperatively associated embroidery stitching mechanism which functions to produce similar clocks, or other ornamentations, in each of the stockings on the frames. The hosiery holding frames, or devices, are generally of a rectangular shape and are open at the front, rear. and bottom so that each device may be positioned Vertically over its respective shuttle Y55 arrangement of the machine. When a stocking 1937, Serial No. 132,378

is properly mounted on one of these hosiery holding devices the hosiery fabric at the front open side of the device is positioned between the shuttle arrangement and its cooperating stitching needle.

When the machine is in operation, all the stocking holding frames are moved as a unit in accordance with pattern controlled means, relative to the stitching mechanism which is mounted in fixed position, and in this manner the same designs are embroidered in all the stocking fabrics. After a design has been embroidered in one side of the stocking, each frame is reversed so that the fabric extending over the rear open end of the frame comes between its respective shuttle mechanism and needle, and the embroidering operation is repeated;

My invention is concerned with the shuttle mechanism of the general type referred to. V

In the accompanying drawings, only those well known partsof a hosiery embroidery machine are shown in association with my invention which are helpful to an understanding of the function'and operation of the invention. For additional information concerningcorelated and'associated parts above mentioned patent and patent application.

Referring to the various figures of the drawings, it designates a tubular standard or support, which is provided at itslower end with a base plate it, and at its upper end with an angularly positioned guide block 42, for a shuttle i3 and shuttle mounting i l both of whic h are arranged to be reciprocated in a. ,guideway lZct of the guide block i 2 during operation of a needle i5 back and forth through the hosiery fabric, indicated by the numeral iii, as it entersand is withdrawn from its-guide slot ll in'the guide block l2 during cooperation with the shuttle l3.

The base plate H is secured by means of bolts l8 and nuts E9 to a fixed bar 2B which extends the full length of. the machine and has as many additional shuttle devices similarly mounted thereon as desired.

Beciprocation of the shuttle l3, and its mounting it, is effected by means of an actuator'or bar 22, which also extends the full length of the machine and cooperates with the other shuttle devices in similar manner. The actuating bar 22 has uniform but limited composite movement vertically and horizontally with respect to the shuttle device, and the vertical component of this movement is transmitted to the shuttle l3 and its mounting M by means of a movement transmitting member, or slide rod 23, and a motion translating element or link24 which is ing its reciprocatory movements.

pivotally connected at 25 with the rod 23, and at 26 with the shuttle mounting l4. Fig. 1 shows actuator rod 22 substantially in its lower or extreme position when moved in one direction, and Fig. 3 in its other, or extreme upper position.

The rod 23 is arranged to freely slide in a guide 21, integrally formed on the support In, and a guide aperture 28 in base plate H, a compression spring 29 being provided on the rod 23 intermediate the guide 2'! and an adjustable collar 31 fixed to the rod 23 by a set screw 32. The spring 29 acts to urge the rod 23 downwardly against the lifting action of the actuator 22, and its pressure may be regulated, as desired by selectively positioning the collar 3| on the rod 23.

In order that the shuttle l3 may be'properly positioned for most eflicient cooperation with the needle I5, the rod 23 is provided with'a rod length adjusting sleeve 33'.which is internally threaded as at 34 and mounted on the lower threaded portion 23a of the rod 23,'a lock nut 35 being provided for locking and unlocking the sleeve 33, as desired. An anti-friction roller 36 is rotatably secured to the lower extremity of the sleeve 33, and is adapted to at all times rest on the actuator bar 22, and during movement of the latter to rotate so as to reduce the contact friction between these parts to a minimum.

The shuttle mounting I4 is provided at its lower end with a cross pin'3'! against which the shuttle l3 rests, and a' pivotally mounted finger 38 at its upper end. The finger is ordinarily positioned crosswise of the mounting 14, as shown in Fig. 5, to prevent the shuttle l3 from escaping or'flying out of the top of the mounting l4 dur- Whenit is desired to remove the shuttle l3 to permit replacement of the yarn bobbin (not shown) within the same, or for other reasons, the finger 38 is moved to' its vertical position indicated by the dot-andthe side of mounting l4 by a screw or rivet 4| cooperates with the pivoted end of finger 38 .to

yieldably hold the same in either the vertical or horizontal positions indicated in Fig. 4. 7

To facilitate precise and easy sliding action of the mounting I4 in its guideway l2a of the guide block l2, the mounting I4 is provided with a rib 42 which extends lengthwise of the mounting l4 and is arranged to slide in a groove 43 of the block [2. i

The upper part of my novel shuttle device extends upwardly into a fabric or hosiery holding frame 45, as usual, so that the fabric, indicated at H5 in Fig. 2 maybe embroidered when the needle 15 and shuttle mechanism cooperate during operation of the machine, all as well understood by those skilled in this art. 7 f

The frame 45 is constructed and mounted on a pattern actuated bar 46, as explained in my above referred to patent and patent application.

During operation of the machine, the movements of the needle I5 and the actuator 22 are cooperatively synchronized with the movements of the hosiery holding frame 45 to effect embroidering of .a clock or other design in the, fabric I6. only illustrated one shuttle means in the draw ings, as many similar means may be provided in the embroidery machine, as desired, all operated in unison, and each coacting with its respective needle mechanism and hosiery frame in the manner described, and set forth in my above mentioned patent and patent application.

Of course, my improvements in shuttle mech- It will be understood that although I have anisms, .as specifically shown and described in connection with hosiery embroidery machines, can be changed and modified in various ways without departing from the invention herein disclosed and hereinafter claimed.
